Just added this plugin as it's exactly what I needed. However, after having set all values to 0 except for the max width of the images uploaded in a Page/Post, which I set to 800, but I still get strange results. I picked a landscape image that was intentionally massive (more than 2000px wide), and it resized it to be 600 across, not 800. Any ideas?
600, I should point out, is what I've set as the size for the "Large" thumbnails. Should this affect it?
